JESS F. IIINCK, F DEVILS LAKE, NORTH DAKOTA, ASSIGNOR-OF TWO- THIRDS TO OLUF- WM. LARSEN NORTH DAKOTA.

AND JAMES L. LARSEN, 'o LAKOTA,

To all whom it may concern."

Be it known that I, JEss F. HINCK, a 'citi' zen of the United States, residing at Devils Lake, in the county of Ramsey and State of v panying drawings. IO

My invention relates to improvements in friction gearing for cream separators and other machines.

The object of the invention isto rovide a mechanism of this character whicrwill beexceedingly light and easy running, and at the same time-strong, durable and comparatively inex ensive. 7 Other 0 jects and advantages of my invention, aswell as the structural fea ures by means of-which these objects are etained, will be made clear by an examination of the following specification, then in connection with the accompanying rawings, in which the same reference numerals indicate corresponding parts throughout, and in which:

Figure 1 is a front elevation, -with parts-in section, of my improved friction gearing; Fig. 2 is a side elevation of the same; and Fig. 3 is a detail sectional view through the bevel gearing which causes the operating levers to move simultaneously'in opposite directions,

Theembodiment of my invention'shown in.

the drawings, comprises a cone friction wheel or disk 1 and two friction wheels 2 .and 8, which latter have their peripheries cushioned preferably by means of pneumatic rubber tires 4 or the like. These wheels 2 and 3 may be of any'suitable form and construction,but

' them, as clearly shown in Fig.1 -45 I preferably employ'wheels similar to the ordinary bicycle wheels. Theyare disposed at diametrically-opposite points with respect to the cone disk 1 w 'chthey drive, and saiddisk has its friction face 5 curved to receive is keyed or otherwise secured to a shaft 6 which is here shown as the vertical shaft of a cream separator and-which has mountedupon its upper end a separator bowl or receptacle 7' of any desired form and construction.

This

driven shaft 6 is j'ournaled in a bearing 8 in a suitable frame or support consisting of np rights 9 prg'v ecting from a base 10 and con nected by a cross-bar 11. To reduce friction and prevent end thrust of the shaft 6, I place Specification of Letters Pant. Application filed February 24, 1906. Serial No. 302,771-

The disk 1- Patented May 21, 1907.

an annular row'of bearing balls 12 between opposing grooves or raceways formed concentrically in the upper face of the disk 1 and the under face of a circular plate 13 which is disposed beneath the cross-bar ll.

The lower portion of the shaft 6 is mounted in a bearing 14 here shown upon a bracket secured to the base 10. The drivingfriction wheels. 2 and 3 are secured upon alining shafts 15 and 16 which are j ournaled in bear? ings in the uprights 9 and have fixed upon their outer ends cranks 17. Thelatter pro jectin opposite directions and are connected by links or pit'man rods 18 to opera-tinglevers 19. These levers are disposed upon opposite sides of the machine and have their lower ends pivoted at 20 upon'the base 10 and their ends provided with handles 21, so that when they are oscillated simultaneously in opposite directions the wheels 2 and 3 will be rotated in opposite directions toimpart their movement to the disk 1 andhence the shaft 6.

In order to cause the levers to move in uni I key or otherwise secure bevel gears 22 upon the inner ends of the shafts 15 and 16, which ends turn in recesses or seats formed in a bearing block 23' through the center of which theshaft 6 extends and in which it rotates. These opposing gears 22 mesh with upper and ,lower bevel .pinions 24 which turn free y upon By means of this construction, it will be seen that, one of the gears 22'cannot turn faster must work in unison.

tages of the invention ,Will be readily understoodfrom the foregoing description taken in connection with the accompanying drawings; hen the levers are oscillated forat the same time, the whee tate inopposite directions and imparttheir movement to the disk 1 by reason of their frictional engagement therewith; Owing to the pneumatic tires upon the wheels 2 and 3 and the shape of the disk 1, the operation of the gearing will ,be exceedingly light and less extent, the frictional pressure of the wheels 2 and 3aga1nst the diskl may be varied as desired' The provision of; the

Having thus described my said invention, What I claim as new and desire to secure by Letters Patent of the United States, .is:

1. The combination, with a driven shaft and two alining drive shafts, of a friction disk upon said driven shaft, drive wheels upon said drive shafts and engaged with said friction disk, and means for rotating said drive shafts simultaneously in opposite directions.

2.; The cdrnbination with a driven shaft and two alining drive shafts, of a friction disk upon said driven shaft, drive wheels upon.

said drive shafts to frictionally engage said disk, crank and lever devices for operating said drive shafts, and bevel gearing between said drive shafts for causing them to move simultaneously in opposite directions.

3. The combination, with a driven shaft and two alining drive shafts, of a friction cone disk u on the driven shaft, drive Wheels upon said rive'shafts to frictionally engage said friction disk, bevel earing connecting the inner ends of said drive shafts to cause them to turn. simultaneously in op osite directions, cranksupon the outer ends of said drive shafts, a pair of operating levers, and

links connecting said levers and said cranks.

4. In a machine of the character described, the combination with a frame or support, a driven shaft, and alining drive shafts, of a friction disk upon said driven shaft, an anti- 5. In a machine of the character described,

the combination with a frame or su port, a driven shaft and alining drive shats, of a friction disk upon said driven shaft, ball bearings between said support and said disk, friction drive wheels upon said drive shafts and engaged with said disk, bevel gears fixed upon the inner ends ofsaid drive shafts, bevel pinions loosely mounted u on said driven shaft and in mesh with sair gears, a bearing block loosely mounted upon said driven shaft and having bearing recesses to receive the inner ends of said drive shafts, cranks upon the outer ends of said drive shafts, hand levers pivoted upon said support, and links connecting said levers and said cranks.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

JESS F. HINCK.
